The Coal Industry Nationalisation Act 1946 provided for the complete nationalisation of the coal industry and the establishment of a National Coal Board. The Board was constituted in 1946 and in 1947 the assets of 800 or more private collieries and the contracts of their employees were transferred to the Board, along with other assets of the earlier Coal Commission.

In 1986 the name was changed to the British Coal Corporation. The British Coal Corporation has subsequently been de-nationalised.
